Does every change in the political wind mean that we must change our foreign policy? No. It doesn't. We are on the backward slope of the war and it's only a matter of time until we start bringing troops home. 2007 was already expected to see a significant reduction of troops in Iraq. I'm sure that will happen. The Democrats are not the driving force behind that, and shouldn't been seen as such. If terrorists think they can influence our political dynamics forcing troops from Iraq, that would be a very damaging thing. Buck up. We'll be out of there in due time.
When you have a total vote of no-confidence in our foreign policy, like today, that must be heeded. This isn't about random winds. This was a repudiation of Rumsfeld and Bush and the way the war was conducted and the reasons for going to war.
